Title: Sensor for abnormal operation of cutting tool of machine tool
Inventor: UMOTO TADASHI
IPC: B23Q17/09
Filed: 1979-07-10
Abstract: PURPOSE:To sense the abnormal operation of the cutting tool by detecting the pressing force in the forward movement of the tool driving member and the cutting tool displacement in the forward movement of it. CONSTITUTION:Marks X1-X5 represent the displacement of a drill bit 1 from a reference position, and marks P1-P5 the pressing force of the drill bit 1 at given displacement positions. For example, when the displacement section of the drill bit 1 is X2<X<X3, the normal pressing force in the section is P2 in FIG.(a). However, when the drill bit 1 is broken as shown in FIG.(b), the pressing force in the section is P1(<P2). Moreover, when the drill bit 1 is in an abnormal condition as shown in FIG.(c), the pressing force in the section is P5(>P1). Consequently, in this case, when the pressing force is not equal or almost equal to P2 in the specific displacement section (X2<X<X3), the drill bit 1 is found to be in an abnormal operation condition.

Title: Formation of oxide film
Inventor: HAYASHI YUTAKA
IPC: H01L21/316
Filed: 1988-04-11
Abstract: PURPOSE:To form an oxide film where the film thickness differs with difference in step in accordance with the plain shape and the shape of sectional area in the stage-difference part shows a smooth slope, by subjecting the surface of the silicon part to thermal oxidation and growing a silicon oxide film. CONSTITUTION:Impurities are introduced to the silicon surface of a substrate 1 by diffusion to form a concentration area of high impurities, the area within the substrate at the outside is a low-impurities concentration area, and a structure where the diffusion depth of impurities is reduced toward the outside of the area when introducing impurities by diffusion. If the surface side of the substrate 1 is subject to thermal oxidation in this status, the film thickness of a silicon oxide film 4 which grows becomes proportional to the concentration of impurities in the substrate 1. In this thermal oxidation, a boundary area 3 further expands its width and the concentration inclination at this area becomes further flat. It allows a silicon oxide film with a smooth sectional-area slope at the step-difference part of film thickness to be easily and positively formed.

IPC: B29C45/50
Filed: 1990-04-05
Abstract: PURPOSE:To enable the above method to control a screw position even during pressure control, by a method wherein when a positional deviation or a speed deviation becomes respectively established value or lower, changed over to a positional control and when they exceed the established value, changed over to pressure control. CONSTITUTION:A switch SW is changed over to a positional control side and positional and injection speed control are performed in the injection speed control section of an injection process. When the subject machine is in the pressure control section such as a dwell process, if a value of a positional deviation ex or a speed deviation ev is not exceeding an established value, the positional and speed control are performed as they are. However, when the value exceeds an established value, the switch SW is changed over and pressure control is executed so that detected pressure Pr becomes established pressure Ps. Then the positional deviation ex and speed deviation ev are obtained even during the pressure control and when the positional deviation ex and speed deviation ev become the established value or lower, changed over to a positional control side and the positional control is performed.

Title: Memory device
Inventor: ISHIZAKI OSAMU
IPC: G11C11/34
Filed: 1987-04-09
Abstract: PURPOSE:To easily and surely write information in a designated storing section, by delaying the timing of changing the state of R/W signals. CONSTITUTION:An R/W signal delaying circuit 7 delays the rise of R/W signals (f) and sends its output signal (i) to a writing circuit section 6. Moreover, delayed WI signals e1 are sent to the circuit section 6 from a generating section 5. When ADD signals (a) and (b) change, the signals e1 which inhibit writing are generated and, while the signals e1 are '1', a readout state is set at the inside regardless of the state of the signals (f). The internal writing state is maintained even if writing is inhibited by the signals e1 or even after the signals e1 are disconnected by the internal R/W signals (i). Therefore, information can be written surely in a designated storing section 3 even in an ordinary writing cycle which is not a continuous writing cycle.

Title: Light receiving circuit
Inventor: MINAMI TAKANORI
IPC: H04B10/572
Filed: 1981-06-10
Abstract: PURPOSE:To prevent a drop of the response speed for a light receiving circuit, by applying a certain level of voltage to an APD via a gate circuit in case the optical input level is higher than a certain value. CONSTITUTION:The control voltage VC is applied to an APD11 of a light receiving circuit via a high voltage generating circuit 12. As the optical input level increases, the voltage VC lowers in order to decrease the increment factor of the APD11. Accordingly the output voltage of the circuit 12 also lowers, and at the same time the voltage VAPD which is applied to the APD11 also lowers.  With the reduction of the voltage VAPD, the increment factor of the APD11 is fixed at 1. Then the response speed of the APD11 is reduced when the increment factor of the APD11 is less than a certain level Vmin. Thus a gate circuit 13 is opened at the level Vmin, and the Vmin is supplied from a constant voltage circuit. As a result, the voltage supplied to the APD11 does not lower less than Vmin to prevent the reduction of the response speed.
